PORTABLE BRlCK-HACK.

SPECIFICATION forming part of Letters Patent No. 326,812, datedSeptember 22, 1885.

Application filed June 16, 1885.

To all whom it may concern.-

Be it known that we, Maroon XVALKER and EPHRAIM MINER, citizens of theUnited States, residing at Yankton, in the county of Yankton andTerritory of Dakota, have invented certain new and useful Improvementsin Portable Brick-Hacks, of which the following is aspecifieation,reference being had therein to the accompanying drawings.

Figure 1 is a perspective view of this device as in use. Fig. 2 is aperspective view of the frame and carriage ready for taking up the hack.

The object of our invention is to provide a means whereby a large numberof bricks may be easily carried from place to placein a brickyard orother place with no more help than is ordinarily employed to carry amuch smaller quantity.

Another object of our invention is to provide a device for carryingbricks which shall be so etlicient as to render the accidental droppingof a brick-hack full of bricks practically impossible.

In the usual way of carrying bricks from the yard to the kiln, or viceversa, there is much danger of accidental stumbling, and conse quentdropping of bricks, which, besides being the source of much annoyance,is very disadvantageous, as much time is thus lost, and the loss causedby the breaking of bricks is also considerable. Again, by carrying thebricks in the hands in the old way, all of the strain comes directly onthe arms of the carrier, and he can only carry a comparatively smallnumber of bricks, whereas by the cur ployment of our device the sameperson can carry many times the number which he could carry in his armsor on a hack in his hands, and with absolute safety as regardsaccidental dropping-first, because the hack, when be ing carried by ourdevice, is so close to the ground that the fall would cause no materialconcussion, and, second, because the person using the machine, even ifhe were to fall, would not drop the bricks, as the machine will supportthe bricks independent of the operator.

This device is designed especially for handling or moving green bricks.By any other device for that purpose that we know of,

(No model.)

the green bricks, (that is, the freshly molded,) when taken from themachine, are placed into a flat wheelbarrow and carried to the yard,where they are taken from the wheelbarrow and hacked up. \Vhen they aredried they are again loaded on the wheelbarrow to be taken to the kiln.By the present invention they are placed directly from the machine uponthe hack and wheeled to the yard, set down, dried, and then taken by thecarriage to the kiln. Thereby a large part of the labor in loading andunloading the hack is avoided, and in a large brick-yard at least fiftyper cent. of this kind of labor is saved.

Having set forth the main object of our invention, we will now proceedto describe it in detail.

It consists in a novel construction, arrangement, and combination ofparts, which will be hereinafter explained, and more especially.

pointed out in the claims.

In the accompanying drawings, A designates the frame, secured togetherby any suitable number ofcross-bars, the front one, a, of which is usedas a handle in raising or lowering the frame or moving the carriage. Therear bar, a, has on its outer sides the hooks b, the purpose of whichwill be described hereinafter. At the rear end of the frame A are twoeccentric crank-arms, O C-one on each sidethe lower outer ends of whichform the axles for the wheels D l).

Extending diagonally downward and backward from the side bars of frame Aare the braces E Eone on each sideand from the rear of the same bars area pair of secondary braces, E E-one 011 each side-extending diagonallydownward and forward, and crossing the arms E E at c. This portion ofthe device we call the cart or carriage. The skeleton frame F,preferably made of strong wire, is hung by its horizontal bar or piece],or in any suitable way, upon the hooks b on the rear bar of the frame A.Each of the flaring wires or bars ff on each side has hooked ends f".-These ends are adapted to engage under the projections g on each side ofthe hack G.

It will be observed that when the device is in the position shown indotted lines in Fig. 2, the front end of the frame A being raised,

ICO

the rear of the frame will be lowered and the frame F will come nearerthe ground, and so ready for its ends to beengaged on thesideprojections of the brick-hack.

The operation of this device is as follows: The hack being properlyfilled or loaded with brick, the carriage is wheeled up to the end of vthe hack and is moved along over it, the wheels being astride the hack.Then by lifting up the forward part of the frame the ends f 3 of theframe F are lowered and can be engaged under the side projections of thehack. Now, by pressing down on the front bar or handle of frame A, theends of the longer downwardly-projecting side bars will be the fulcra onwhich the frame F will be caused to raise the hack till it swings freefrom the ground and the load of bricks is in a position to be wheeledaway. To unload, reverse the above operation. The ends of the shorterside bars are supports for the frame A when the carriage is not used. Byhaving two braces on each side the frame is very much stronger.

It is evident that in the mere detail of construction there may be manymerely mechanical changes in the, above construction which will in nomanner change the nature or scope of our invention.

We are aware that a hive-truck has been constructed similar to ourdevicei. e., it was provided with two wheels and a pair of handles. Italso had a' system of levers which served to facilitate the raising of ahive from the ground and suspending the main part of the weight from theaxle; but our device is designed especially for carrying flatbrick-hacks, and it is much less complicated, while it accomplishes theresult aimed at without the employment of any levers except the handles,which serve as a means for steadying the truck. We therefore disclaimthe hive-truck above referred to; and

What we desire to secure by Letters Patent, and what we really do claim,is

1. In a brick-carrying machine, the combination of the main frame andthe eccentric crank-arm with the wheels and suitable supports andsupporting-frame for the hack, as set forth. v

2. In a brick-carrying machine, the combination of the main frame, thewheels, and crank-arms with the hooks b b at the front end of the frame,and frame F, having the hooked ends, as set forth.

3. In a brick-carrying machine, the frame, the cross-bars a and a, thehooks b b on the latter forward of the axle-supports or eccentric arms,and the hooked rods F F, with the arms f as set forth.

4. In a brick-carrying machine, the main frame having side braces orsupports, E E, the latter serving the double purpose of a brace and asupplemental handle, the crankaxles G, the hooks b b, and the hookedrods F F, all combined in the manner and for the purpose set forth. r

In testimony whereof we affix our signatures in presence of twoWitnesses.
